Current Topic: Rational Functions - Expressions and Equations


In this unit you will be exposed to simplifying rational expressions, adding and subtracting rational expressions, multiplying and dividing rational expressions, solving rational equations. We may even get into some graphing!

Some common questions you may have as we begin our unit on Rational Functions:

  1. What is a rational expression?

  2. How do I simplify a rational expression?

  3. What is a rational equation?

  4. How do I solve a rational equation?
  5. Where are rational functions found in the real world?

3. What is a rational equation?
A rational equation is simply a rational expression set equal to something. It could be set equal to a number, to a polynomial, or to another rational espression.

4. How do I solve a rational equation? Check out this video - we will work our way up to the more involved example used in the 2nd half of the video.


5. Where are rational functions found in the real world?
